Martha Stewart's net worth is estimated at around $400 million, built from decades of magazines, cookbooks, TV shows, and licensing deals for her lifestyle brand. That figure is well down from the roughly $1 billion "paper fortune" she held briefly after her company's 1999 IPO -- a peak that collapsed in half following her 2004 conviction in the ImClone insider-trading case, which included a five-month federal prison sentence.
Since then, Stewart has rebuilt around new ventures: an unlikely hit partnership with Snoop Dogg, a CBD supplement line, a recurring judge's seat on Food Network's "Chopped," and -- at 81 -- a cover shoot for the Sports Illustrated Swimsuit Issue.

Early Life and Building the Brand
Martha Stewart was born Martha Helen Kostyra in Jersey City, New Jersey, to Polish-American parents Edward and Martha Kostyra. She studied history and architectural history at Barnard College, worked briefly as a stockbroker, and later ran a catering business out of her home in Westport, Connecticut, that became the seed of her media empire. Her 1982 book "Entertaining" launched a publishing career that expanded into magazines, television, and home goods, culminating in Martha Stewart Living Omnimedia's 1999 initial public offering -- a debut so strong it made her a billionaire on paper for a stretch, before the stock settled back down to earth in the months that followed.
The ImClone Insider-Trading Case
In December 2001, Stewart sold shares of ImClone Systems the day before the company's stock dropped on news that regulators had rejected its cancer drug -- a sale prosecutors said was made on a tip from her broker. She was never charged with insider trading itself; the case that went to trial centered on what she did afterward. In March 2004, a jury convicted her of conspiracy, obstruction of justice, and making false statements to federal investigators about the sale. She was sentenced to five months in federal prison, followed by five months of home confinement with electronic monitoring, and served her time at a federal prison camp in Alderson, West Virginia, in 2004 and 2005. The scandal wiped out roughly half her net worth and forced her off her own company's board for a time -- though she returned to it in 2011 and became its chairwoman again the following year.
Rebuilding the Brand
Stewart's company was sold to Sequential Brands in 2015 and then to Marquee Brands for about $175 million in 2019, but she has remained the public face and creative force behind the brand under both owners. Her partnership with Snoop Dogg -- an odd-couple VH1 cooking show, "Martha & Snoop's Potluck Dinner Party," that ran from 2016 to 2020 -- introduced her to a younger audience and led to a joint podcast. She has also worked as a cannabis advisor for Canopy Growth since 2019, launched her own CBD gummy line in 2020, and become a recurring judge on Food Network's "Chopped" since 2018.
Personal Life
Stewart married Yale law student Andrew Stewart in 1961; the couple had a daughter, Alexis, in 1965, separated in 1987, and divorced in 1990. She kept his surname, which had by then become central to her brand, and has not remarried.
Recent Milestones
Stewart made headlines again in May 2023 by appearing on the cover of the Sports Illustrated Swimsuit Issue at age 81, becoming its oldest cover model. In 2024, Netflix released "Martha," a documentary directed by R.J. Cutler covering her rise, the ImClone case, and her comeback, and she published her 100th book, "Martha: The Cookbook." In 2025, she began co-hosting the NBC cooking competition "Yes, Chef!" alongside chef José Andrés.
